Electrical installation
WARNING
• The electrical installation may only be carried out by a qualied electrician in accordance
with the instructions provided with the heater.
• As electrical installation regulations di󰀨er from country to country, contactors, cables,
connection components, and enclosures must be selected based on local regulations.
• A main isolator must be installed before all live electrical connections on the heater. This
must be an all-pole isolator that satises the requirements set out in IEC/EN 60335-1
paragraphs 7.12.2, 22.2 and 24.3.
• Pahlén recommends the installation of a residual current device.
• The heater must be connected according to the wiring diagram below.
• The control voltage is connected: for 230 V 1-phase and 400 V 3-phase to L1 and N,
for 230 V 3-phase to L1 and L2.
Note that the control voltage must be tted with a separate fuse of 5-10 amps for the live
electrical connections.
• The heater must be installed in such a way that it cannot be activated unless the circulation
pump is in operation (su󰀩cient ow), i.e. the control current to the heater’s contactors must
be controlled over the pump’s contactors.
• The voltage to the heater must not uctuate more than +5% to –10% in relation to the
specication of the model and type plate.
• The installation method must be chosen in such a way that the temperature limit is not
exceeded for any component at full load.
NOTE!
Installed cables are only test cables. These must not be used for connection.
